@willoneal, it’s possible to this by pointing your write node to the same folder you’re reading from. It’s not done automatically for a couple of reasons, but the #1 reason is so that it’s not easy to overwrite your original files.

Other reasons are because you can have multiple input folders and files, and multiple outputs, so things can get a little tricky- like if you resize an image twice, which one gets saved over the original file?
